Review on 🔌 Grohe 46138000 1/2 in. Quick Coupling: Hassle-Free Connection at Any Size by Daniel Elgee

Easy installation without tools. The only problem is getting access to the connection point on the faucet after installation. The hitch is behind the sink, just below the countertop. The 1.75 lpm quick coupler, which comes straight from the factory to the faucet, restricts water flow so much that we couldn't even get the nozzle to stop. Apparently, in the US, Grohe supplies faucets that meet some sort of flow restriction standard. I read somewhere that the standard is called "California Green" and I can only assume that this has to do with the drought California has been experiencing lately. In any case, the Groho 46 138 000 quick coupler has no flow limitation. So now our blender is working great. The only downside is that the price per part is ridiculously high. $40+ for a small piece of plastic is absurd. The term that comes to mind is price gouging. Still, it works great and completely solved our low water pressure issue.
